A building at Lehigh University was evacuated Monday afternoon after the discovery of a leaking gas cylinder.

Around 12:25 p.m., authorities said there was a gas leak at Iacocca Hall chemical engineering department, according to police radio reports. A mixture of hydrogen and hydrogen sulfide were the chemicals reported in the leak.

The building was evacuated while crews contained the leaking gas cylinder and authorities later determined "there was no danger," according to university spokesman Jordan Reese. By 2 p.m., people were allowed back inside the building.

No injuries were reported.

The evacuation affected a local education meeting with the Pennsylvania acting secretary of education, Pedro Rivera.
